PXH9 is a 96 × 96 mm, high-performance digital controller developed and produced by Yokogawa Electric Co., Ltd., which ensures high-speed and high-accuracy control. With its abundant and flexible input/output points and powerful math function, it can be used for a wide range of applications, including not only temperature control but also pro- cess control of pressure, flow rate, etc.
The PXH9 is a 96 × 96 mm high‑performance digital controller designed for process control such as temperature, pressure and flow. It offers high‑speed control with a 50 ms sampling cycle, ±0.1 % FS input accuracy and a variety of math functions.
The controller provides abundant I/O (thermocouple, resistance‑bulb, voltage, current, digital and analog), optional RS‑485 Modbus‑RTU, IP66 front‑face protection and a compact panel‑mount design (96 × 96 × 81.5 mm). Detailed specifications, alarm functions and communication settings are listed in the datasheet.
| Power supply voltage | 100 V (‑15 %) to 240 V (+10 %) AC, 50/60 Hz |
|---|---|
| Power consumption | 15 VA (100 V AC) or 20 VA (220 V AC) |
| Input sampling cycle | 50 ms |
